Abstract (en)

A low voltage circuit breaker (100) is provided. The low voltage circuit breaker (100) includes a contact system (110) with a first contact (112) and a second contact (114) that are electrically connectable and disconnectable relative to one another. The first contact (112) includes a body (b) having a first layer (11) and a second layer (12), wherein the first layer (11) is arranged on the second layer (12) and is configured to come in contact with the second contact (114) for providing the electrical connection with the second contact (114). The first layer (11) has a first material composition having an Ag content that is higher than an Ag content of a second material composition of the second layer (12). Further, the first material composition has a WC content that is lower than a WC content of the second material composition.
